Powerful Illumination for Outdoor Use

The Sofirn SK40 features a Luminus SFT70 LED with a 6000K color temperature, delivering a maximum output of 3200 lumens with a beam throw of 580 meters, powered by an included 21700 Li-ion battery. It offers multiple modes, controlled by a tail tactical switch and side electronic switch, with the following lumen outputs and runtimes:

Turbo: 3200 lumens for approximately 1 minute (steps down after initial output)
High: 1000 lumens (runtime not specified)
Medium: 300 lumens (runtime not specified)
Low: 50 lumens (runtime not specified)
The flashlight charges via a built-in USB-C port, taking about 2-3 hours with a 5V/2A charger, and includes a side switch indicator that displays voltage for 5 seconds after turning on. It has an IP68 waterproof rating, suitable for submersion up to 2 meters, and features thermal protection to manage heat, though prolonged use on Turbo may generate heat, requiring careful handling.
Durable and Compact Design

The Sofirn SK40 is constructed from aerospace-grade aluminum alloy with a Type III hard-anodized, anti-abrasive finish, offering durability and corrosion resistance for outdoor conditions like camping or patrolling. It measures 155mm in length with a head diameter of 40mm, weighing approximately 132g (including the battery, though exact weight without battery varies by source), making it suitable for pocket or gear carry. The flashlight features a tail tactical switch, a side electronic switch, and a sturdy pocket clip, though the clip may limit tailstanding stability.

Designed for Outdoor and Tactical Use

The Sofirn SK40 3200 Lumen 580m Throw Rechargeable Tactical Flashlight with 21700 Battery for Outdoor Use is tailored for tactical users, outdoor enthusiasts, and professionals needing a reliable light for emergencies, search and rescue, or outdoor activities. For example, its dual-mode switching (duty and tactical modes) provides flexibility for various scenarios, though the dual-switch UI requires practice to navigate modes (tail switch for momentary or constant on, side switch for mode adjustment), and some users note a green tint in the beam. The robust construction and IP68 rating enhance its reliability, but users should avoid direct eye exposure due to its intensity and rinse it with fresh water after use to maintain performance. The SK40's affordable price (around $35-$40 with discounts), included 21700 battery, and tactical design make it a practical choice for outdoor scenarios, offering a balance of power and convenience, though users should plan for heat management and UI familiarity.

Note: Ensure the flashlight is turned off or locked (double-click the side switch to lock out when off) after use to prevent accidental activation, which could drain the battery; the dual switches can be sensitive. Use the included 21700 battery with proper polarity (positive terminal toward the head), and remove the insulating film before first use or charging. The IP68 rating supports submersion up to 2 meters but is not suitable for prolonged diving; avoid submersion beyond this limit. Handle with care during Turbo mode to avoid burns due to heat buildup, and do not shine the light directly into eyes due to its intensity. Store in a dry place to maintain reliability, and use a 5V/2A charger (not included) for optimal charging. Rinse with fresh water after exposure to wet conditions to maintain performance.
